Direct Response Website / Lead Capture Page

I am looking for a professional and creative, yet clean and crisp, direct response lead capture page which then goes to a sales page, and on to a thank you page. The capture page must be compelling and intriguing to encourage prospects to leave their details (I have the copy, but comments will be welcomed). The same goes for the sales page and the thank you page - ultimately a sales focus to close customers. The communication tempo is to be carried out through all 3 pages. DIRECT RESPONSE WEBSITE DESIGN IS CRITICAL. PLEASE ONLY APPLY IF YOU HAVE EXPERIENCE IN THIS. PLEASE PROVIDE SAMPLES OF YOUR PORTFOLIO.
